In the early days of this technology, there were many who saw the potential of these new instruments for environmental measurements and how this technology could be integrated into emissions and ambient air monitoring for the measurement of flux. However, the monitoring community did not embrace ORS as quickly as anticipated. Several factors contributing to delayed ORS use were: • Cost: The cost of these instruments made it prohibitive to purchase, operate and maintain. • Utility: Since these instruments were perceived as “black boxes.” Many instrument specialists were wary of how they worked and how the instruments generated the values. • Ease of use: Many of the early instruments required a well-trained spectroscopist who would have to spend a large amount of time to setup, operate, collect, validate and verify the data. • Data Utilization: Results from path integrated units were different from point source data which presented challenges for data use and interpretation.

Newkome Committee Member Date Dr. Coleen Pugh Committee Member Dr. Chrys Wesdemiotis ii ABSTRACT One of the unique features of living, alkyllithium-initiated, anionic polymerization is the ability to produce a stable carbanionic chain end after complete monomer consumption, which can be followed by reaction with electrophiles to form various end- functionalized polymers. Although a variety of functional polymers have been synthesized in the last few decades, each specific functionalization has had to be designed and optimized individually. Consequently, the development of general functionalization methodologies has drawn recent interest. However, even these general functionalization methods require the use of protecting groups, and the complexity in synthetic routes and the thermal/moisture instability of many protected functional agents have restricted their practical application. This thesis describes a new, general functionalization methodology, combining well-defined, living anionic polymerization with efficient and highly selective, platinum-catalyzed hydrosilation reactions with functionalized alkenes. Well-defined, Si-H functionalized polymers (P-SiH) have been synthesized by sec- butyllithium-initiated, living anionic polymerization in benzene followed by termination with dimethylchlorosilane.

    A Review of Organosilanes in Organic Chemistry • Silyl Protecting and Derivatisation Reagents • Organosilanes as Reducing Agents • Silanes in Cross-coupling Chemistry • Allylsilanes Used to Stabilize α-Carbanions and β-Carbocations INTRODUCTION Organosilanes have varied uses in organic chemistry from the most frequently employed protecting groups to intermediates in organic synthesis. The Acros Organics portfolio of organosilanes is continuously expanding to meet your chemistry needs. In this brochure you will find an overview of four of the most important applications of organosilanes: • Silyl Protecting and Derivatisation Reagents 1, 2 • Organosilanes as Reducing Agents 3 • Silanes in Cross-coupling Chemistry 4 • Allylsilanes Used to Stabilize α-Carbanions and β-Carbocations4 Silyl Protecting and Derivatisation Reagents Silicon protecting groups are probably the most frequently employed of all protecting groups, and modern natural product synthesis is inconceivable without them.5 Silylating agents are mostly used to protect alcohols and phenols, but have also found application in the protection of amines, carboxylic acids, amides, thiols and alkynes. By varying the substituents attached to silicon, the steric and electronic characteristics of the protecting group can be finely tuned, allowing a wide variety of both reaction and deprotection conditions. The leaving group also plays an important role in the reactivity and use of silylating reagents. Whilst chlorotrimethylsilane [product code: 42643] liberates hydrogen chloride on reaction,

The conclusions and recommendations (and their rationale) in this document are intended to be mutually supportive, and should be understood and interpreted together. 1 CoCAM 4, 16-18 April 2013 US/ICCA Cl4Si SUMMARY CONCLUSIONS OF THE SIAR Analogue/Category Rationale These chemicals can be represented by a similar general molecular formula: (Cl)xSi(H)y(Me)z Where Cl = chlorine, x = 1, 2, 3, or 4; Si = silicon [=1]; H = hydrogen, y = 0 or 1; if y = 0, then x = 4 Me = CH3, z = 0, 1, or 2 Chlorosilanes react rapidly when exposed to moisture or polar reagents (those that contain a dissociable H+), producing hydrogen chloride (HCl; CAS No. 7647-01-0) and the corresponding silanols (in general, siloxane oligomers and polymers). The half lives of the monomeric chlorosilanes are expected to be < 1 minute based on data from the structurally similar chlorosilanes dichloro(dimethyl)silane (Cl2DMS) and trichloro(methyl)silane (Cl3MS). Data are not available on the hydrolysis of these compounds. However, the following is expected: ClMe2SiH is expected to hydrolyze to form one mole each of HCl and dimethylsilanol (note that dimethylsilanol can hydrolyze to form dimethylsilanediol (DMSD) ultimately through hydrolysis of the SiH bond, which is pH dependent and occurs most rapidly under alkaline conditions).

"1 Macartney Welborn Synthesis of Hydrogenated Thiol-Silanes for Selective Reactions Engaged Learning Final Report ! Abstract The intention of this experiment is to show the creation of multifunctional thiols from the reaction between various hydrochlorosilanes and mercaptoethanol in an attempt to utilize their distinct properties for practical applications. Multifunctional thiols have many useful applications including use in high-refractive-index lenses,1 heavy metal chelation,2 and degradable plastics.3 Previous work,5 in our lab has explored a class of reactions key to the synthesis of these compounds: the reaction between methylated chlorosilanes with mercaptoalcohols. We extended this reaction to include hydrogenated chlorosilanes. This allows us to produce multifunctional thiols with an additional functionalizable position at the hydrogen, allowing for greater flexibility in regards to practical applications.
